My only recommendation - avoid them at all costs.
Prior to dmil's death. Ambulance ride to ER, ER to room, room to ICU, back to room for one day - discharged to rehab center - next morning back to ER by ambulance,
to regular room, to ICU, to mortuary. 14 days of a roller coaster ride.
Abdominal pain - emergency surgery - 5" intestine removed, infection, body in shock from infection, kidney's shut down, death.
When the ICU doctor comes to her room, she was surrounded by her children. 3:00 in the morning, she is near death, room light is dim. Doctor barges in flips on the
lights and - and I kid you not said, "sorry I am late, I was attending to someone who actually had a chance of surviving". Makes some adjustments on her IV's dips
to make her comfortable, removes respirator and says "she probably will not regain consciousness, only about 6% do". Yep, she did - eyes pop wide open, frightened
by all the family there, unable to talk, passes within the hour.
Doctors may be use to death in the ICU, but I suggest they take some empathy training.
